SPARK-BURNER .AND WATER-HEATER FOR LOCOMOTIVES.

Specification of Letters Patent No. 10,295, dated December 6, 1853.

the sparks, presents an inner lwater surface to their lire, an outer and also central water surface to the heat from the flues of the boiler, and heats the feed water in a reservoir or space betweenr these water surfaces for supplying the boiler; by which the sparks are saved and utilized and the generation of steam increased.

In the accompanying drawings like letters refer to like parts, and Figure 1 is a sectional side view through the apparatus in the smoke boX. Fig.' 2, is a sectional front view of the apparatus inthe smoke box. Fig. 3, is a top view of the apparatus with the cover removed. Fig. L is'a view of half the cover, and one fourth of the grate, detached.4 Fig. 5 is a side view of thel apparatus detached from the smoke box.

A is the front part of the locomotives boiler, showing the iiues, and smoke box containing the apparatus D for consuming the sparks and heating the feed water, of which apparatus, E E, E E are inner and outer concentric pipes joined at the bottom by a curved plate ring; and G G, G G are two other concentric pipes joined at the bottom by a curved plate ring. The two inner pipes are then connected at the top by riveting through a ring, and thetwo outer pipes also by riveting through another ring, forming water spaces between these concentric pipes, communicating at the bottom between the curved plate rings, and at the top a communication between the water spaces is formed by four horizontal connecting pipes N, N, N, N. The space between the pipes G G-G G, is the reservoir where the sparks are received and burned up on a perforated plate or grate I-I H. The air to support combustion is admitted to the sparks,

through three or four vert-ical pipes I, I, I, 55 ,i

which support the apparatus on the bottom of the smoke box. The top of the spark furnace is covered with a perforated plate M, and the sparks are dropped from the spark catchers reservoir C above, through pipes K, K, secured to this cover,.into the spark furnace to be consumed and heat the feed water. The admission of` air is regulated into the burner by the valves O, O.

The Aexhaust pipes L, L, discharge up the.

inner pipe E, E, into the chimney B of the spark catcher. The bottom of the apparatus D should be about twelve inches from the bottom of the smoke box, and the top about four inches from the base of the top arch of the smoke box.

The water is forced into the apparatus by the pumps through t-he pipes P, P, and enters the boiler head or other part of the boiler through the pipes Q, Q.

This apparatus by means of the exhaust steam will draw the sparks out of the smoke box in the manner described in my patent for improvements in spark and gas con-v sumers of 20th February 1849. i

The spark catcher and reservoir from which the apparatus in the smoke box receives the sparks may be made in any known H13/1111er.

The sparks fall from the reservoir above J through thepipes K into the spark furnace, where they are burnt up. The air passes up' through the pipes I, I, I to consume them and' out the perforations ofthe top M and ascends the chimney while the heat. derived'` flTOHlt-hem and the Hues heats the feedwater j I i Y inside of the water space of the apparatus.

What I claim is- The arrangement and application of the two concentric pipes, the curved plate rings, y the pipes I, I, I, the furnace grate I-I, the. A
